摘要:
A silver halide photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer containing silver halide grains which meet the following requirements (1) and (2):(1) the silver halide grains are formed in the presence of an oxidizing agent, and(2) the silver halide grains each have, in respect of distance L from the grain center to the grain surface, a point at which the content of silver iodide becomes maximum within distance L.sub.1 from the grain center to 0.67 L, and a point at which the content of silver iodide becomes minimum within distance L.sub.2 from 0.58 L to the grain surface and, in each grain, the silver iodide content shows a substantially monotonous decease in the range from L.sub.1 to L.sub.2, and(L.sub.2 -L.sub.1)/L>0.20is satisfied.
